You should get a Ford Racing Traction Lock (T-Lok) for the 7.5 Rear end along with the gears that way you're putting the power to both wheels. It's a clutch operated posi-traction. It'll help your launches and you'll have 2-wheel burnouts instead of 1-wheel. You should get the bearing kit too that way the place you're getting it done at has everything for the install or that place you're getting it done at can order the parts. I went to Powered by Ford to get my stuff installed so they knew everything I needed so I didn't bother ordering that. If you plan on doing it yourself (not recomended if you're not an experienced mechanic) then you do need the bearing kit.

Hope I helped!
